M3 (Uber)

M3 (m3db.io) is Uber's open-source metrics + time-series-database platform, built to handle observability at Uber scale during the 2013+ microservice build-out. Engineers query M3 directly for offline analysis or via Grafana dashboards. Paired with Nagios for alerting at scale. (Source: sources/2024-03-14-highscalability-brief-history-of-scaling-uber)

Cited alongside TChannel, Ringpop, Jaeger as part of the in-house platform Uber built to prevent its 2013+ microservice fleet from becoming a distributed monolith — metrics-everywhere-by-default was one of the platform-team standardizations that supplied the data for SRE practices to scale.
